I'm all for buying a CAM and/or Wingers but it would probably be bench options for a plan B instead of changing our 'go-to' formation. How much money would it cost to buy 2 top wingers today? Too much.
And if we fill the spots with any old half-decent players and use the 4-3-3 as plan A, then we're taking a backwards step. No thank you.
Also, not sold on Chiellini at LB, and Ogbonna could do a 'solid' job. Much more than that, i'm not so sure.
